Definitions
- This invention relates generally to a method and apparatus for testing medical electrode systems and, in particular, to a method and apparatus for testing the operating condition of defibrillators and defibrillator electrodes and for providing the user with an indication of the system's condition.
- Defibrillators apply voltage pulses to a patient's heart in response to a life-threatening condition such as cardiac arrest. External defibrillators deliver the voltage pulse through a pair of electrodes placed on the patient's chest or back by the attending medical personnel.
- the primary components of a defibrillator system are the defibrillator, which provides the voltage pulse, and the electrodes, which deliver the voltage pulse to the patient.
- Prior art external defibrillator electrodes consist of a paddle having an electrode face electrically connected to the defibrillator by a cable.
- a conductive gel on the electrode face lowers the electrical resistance between the electrode and the patient.
- Disposable defibrillator electrodes are typically packaged with the gel pre-applied to the electrode face. Adhesive holds the electrodes in place on the patient. With standard reusable electrodes, on the other hand, the user must apply the gel before placing the electrodes on the patient. Handles on the back side of the electrode paddles enable the user to place the electrodes at the desired sites on the patient to hold the electrodes against the patient's skin.
- defibrillator systems One drawback of prior art defibrillator systems is the number of steps required to deploy the electrodes. Because defibrillators are used primarily in emergency situations, deployment and operation of defibrillator electrodes should be quick, easy and reliable. Prior art disposable defibrillator electrodes, however, require the following steps for deployment prior to delivery of the defibrillation pulse: connection of a cable to the defibrillator; inevitably, untangling of the cable; removal of the electrodes from their package; removal of the release liner covering the conductive gel over each electrode face and any adhesive surrounding the electrode; visual inspection of each electrode to determine whether it is usable; and application of the electrodes to the patient. Each of these steps takes time, and time is of the essence when trying to save a patient's life.
- a defibrillator system providing an indication of the condition of the defibrillator and defibrillator electrodes before deployment and placement on the patient.
- Patient simulation units are available to test the operation of external defibrillators.
- the defibrillator output cable i.e., the conductors leading to the electrodes, is connected to the simulation unit input.
- the defibrillator is then discharged as if the cable were attached to electrodes mounted on a patient.
- the simulation unit measures the defibrillator output pulse and gives an indication of the operating condition of the defibrillator. Because the defibrillator electrodes are not part of the test circuit, however, the simulation unit does not give any indication of electrode condition.
- performing the test with patient simulation units adds to the burden of highly paid medical personnel, thereby raising the costs of the patient's care. What is needed, therefore, is a defibrillation system condition indicator that tests the electrodes and perhaps other parts of the defibrillator system automatically while the defibrillator is not in use.
- This invention provides a defibrillator and electrode system that gives the user a visible and/or audible indication of the condition of the electrodes and other parts of the defibrillator system prior to deployment of the electrodes and use of the defibrillator.
- a patient simulation and analyzer circuit within the defibrillator periodically tests the condition of the system and provides the user with a visual indication of the system's condition.
- One preferred embodiment of an electrode system useful for practicing this invention comprises a flexible substrate having a folded, undeployed position and an extended, deployed position. The substrate supports an electrode, an electrode tester conductive pad, and the electrical connections between the defibrillator and the electrode and between the conductive pad and the patient simulation and testing circuit. In its undeployed position, the electrode contacts the conductive pad to complete a circuit from the defibrillator, through the electrode to the patient simulation circuit.
- the flexible substrate has a rolled or wound undeployed position and an unrolled or extended deployed position.
- the substrate supports a pair of electrodes, a pair of electrode tester conductive pads, and the electrical connections between these elements and the defibrillator and patient simulation circuits.
- the electrodes In the substrate's undeployed position, the electrodes contact their respective conductive pads to complete a circuit from the defibrillator, through the electrodes to the patient simulation circuit.

- FIG. 11 is a side cross-sectional view of the electrode system of FIG. 10 with the electrodes partially deployed.
- FIG. 1 is a block diagram demonstrating the method and apparatus of this invention as applied to a defibrillator system.
- the defibrillator system 10 includes two or more electrodes 12 selectively connected to a standard defibrillator circuit 14 through an electrode interface 16.
- the defibrillator circuit applies a therapeutic voltage or current pulse to a patient through the electrodes under conditions controlled by logic within or associated with the circuit.
- the defibrillator may also receive information regarding the patient's heart activity from the electrodes in the form of ECG signals.
- the electrodes may be configured as described below or, alternatively, may be any defibrillator electrodes known in the art.
- a patient simulator 18 is also selectively connected to the electrodes through interface 16.
- a defibrillator system analyzer 20 connected to the defibrillator circuit 14 and the patient simulator 18 controls the operation of the defibrillator circuit 14 during a test procedure, receives test information through the patient simulator 18, analyzes the test information, and indicates the test results via indicator 22.
- a power source 24 supplies power to the system.
- the operation of the system of FIG. 1 is as follows.
- the system may be used to test the ability of the defibrillator circuit and electrodes to deliver a defibrillation pulse to a patient.
- Conductors leading from at least two electrodes are connected to the defibrillator circuit via an electrode interface.
- the electrode surfaces themselves i.e., the portion of the electrodes that would be mounted on the patient during normal operation of the defibrillator, are electrically connected to the patient simulator, also via the electrode interface.
- a defibrillator test pulse is delivered from the defibrillator circuit to the electrodes, and the effect of the test pulse is measured at the patient simulator by the analyzer.
- the test pulse may be a voltage pulse of any magnitude, including but not limited to voltage magnitudes used for actual defibrillation. In that case, the analyzer will measure the current flowing through the patient simulator.
- the test pulse may also be a current pulse of any magnitude, in which case the analyzer will measure the voltage across the patient simulator. Other suitable tests will be apparent to those skilled in the art.
- the analyzer activates the indicator to show that the defibrillator is not operable.
- the indicator may be a visible indicator such as a light or a written message on a display, an audible sound, or any other suitable means of communicating an inoperable condition to the user.
- the system may also be used to test the response of the logic portion of the defibrillator circuit to a signal originating with the patient.
- conductors leading from at least two electrodes are connected to the defibrillator circuit via an electrode interface.
- the electrode surfaces themselves i.e., the portion of the electrodes that would be mounted on the patient during normal operation of the defibrillator, are electrically connected to the patient simulator, also via the electrode interface.
- a signal substantially similar to an ECG signal derived from a patient in ventricular fibrillation is generated by the patient simulator and delivered to the defibrillator circuit via the electrodes and electrode interface. In normal operation, the defibrillator should deliver a defibrillation pulse to the patient in response to such an ECG signal.
- the ECG test may also be used to determine the response of the defibrillator circuit to a normal (non-fibrillating) ECG signal from a patient.
- conductors leading from at least two electrodes are connected to the defibrillator circuit via an electrode interface.
- the electrode surfaces themselves i.e., the portion of the electrodes that would be mounted on the patient during normal operation of the defibrillator, are electrically connected to the patient simulator via the electrode interface.
- a signal substantially similar to an ECG signal derived from a patient with a normal ECG, i.e., not in ventricular fibrillation, is generated by the patient simulator and delivered to the defibrillator circuit via the electrodes and electrode interface. In normal operation, the defibrillator should not deliver a defibrillation pulse to the patient in response to such an ECG signal.
- the analyzer monitors the output of the defibrillator circuit logic to the test ECG signal. If the defibrillator circuit logic indicates that a defibrillation pulse is required, then the analyzer activates the indicator to show that the defibrillator is not operable.
- the indicator may be a visible indicator such as a light or a written message on a display, an audible sound, or any other suitable means of communicating an inoperable condition to the user.
- the frequency of any of these tests may be chosen to meet the system's requirements.
- the power required for the defibrillator pulse tests may be so high that the frequency of this test must be limited in order to preserve battery life in battery-operated defibrillators.
- the analyzer could monitor battery level continuously.
- FIG. 2 is a circuit schematic showing one way of implementing the principal elements of the defibrillator system of the preferred embodiment.
- the portion of the schematic corresponding to the electrodes and electrode interface blocks of FIG. 1 is enclosed by a dotted line 202 and is referred to as the electrode apparatus or electrode system.
- the electrode apparatus 202 includes a pair of electrodes 204, conductive gel layers 206 covering the electrodes, and a pair of test pads or contacts 208 shown here to be in electrical contact with gel layers 206.
- the defibrillator system of this invention has a patient simulation and test circuit 220 to monitor the condition and integrity of the system prior to deployment of the electrodes and application of the electrodes to a patient.
- microprocessor 218 sends a series of test signals to D/A converter 222, which converts the signals to their analog equivalent and transmits the signals to test pads 208 via conductors 224.
- Electrodes 204 retrieve the test signals as if the test signals were actual patient ECG signals and sends the signals back to the microprocessor through the ECG monitor circuit described above.
- the microprocessor determines from the incoming test ECG signal that a therapeutic pulse is not required, the system is faulty, and the microprocessor indicates the fault on a fault indicator 226. If, on the other hand, the microprocessor determines correctly the required course of action, the fault indicator is not activated.
- the system If the system passes the ECG tests, it then performs a defibrillator test by generating a pulse through its normal pulse generating circuitry and sending the pulse to the electrodes 204.
- the microprocessor sends a charge command to a charge controller 230, which begins charging capacitor 232 in a known manner from power supply 234.
- a charge controller 230 which begins charging capacitor 232 in a known manner from power supply 234.
- switch relay 228 moves switches 212 to their other position. This switch position permits the pulse circuit to discharge the capacitor to deliver a damped sinusoidal shock to the electrodes.
- the pulse transmitted by the electrodes through conductive gel layers 206 to test pads 208 is monitored by the test circuit 220 across a patient load simulator 236.
- the signal is reduced by a divider circuit and sent to microprocessor 218 via A/D converter 238. If the pulse received by the microprocessor does not meet predetermined criteria (such as voltage levels and signal waveform shape), the microprocessor indicates a system fault by activating fault indicator 226. So long as the system passes the tests, the tests are repeated periodically until the electrodes and their gel layers are removed from test pads 208 as determined by a deployment detector 240.
